Created attachment 301268 [details] Dmesg log with failed hibernation attempt Starting from 5.18.4 my notebook (Dell Latitude 3340) won't hibernate - hibernation fails with dmesg errors related to xhci_hcd. I'm attaching dmesg log with failed hibernation attempt. Problem goes away after reverting commit 63acaa8e9c65dc34dc249440216f8e977f5d2748 (USB: hcd-pci: Fully suspend across freeze/thaw cycle). After reverting this commit on linux 5.18.6 my system can again successfully hibernate.
